The bad news is that online criminals can actually exploit increased awareness about security for their own malicious ends.
Take one current malware campaign, for instance, which has been spammed out widely posing as a security update from payroll processing company ADP.
The emails, which have subject lines including "ALERT! From ADP: 2013 Anti-Fraud Secure Update" and "2013 Anti-Fraud Secure Update", have a ZIP file attached containing a malicious payload.
Part of the malicious email reads:
2013 Anti-Fraud Secure Update
Dear Valued ADP Client,

A regular computer user who has been following the security news about patches for Internet Explorer and Java might well think they're being smart if they open the attachment... but the truth is that they will be falling straight into the malicious hackers' trap.
Sophos products detect the malware contained inside the attached "2013 Anti-Fraud Secure Update.zip" file as Mal/FakeAV-OY, a fake anti-virus program.
If you're running a firewall, it may block the fake anti-virus product's attempt to connect with the outside world.
Fake anti-virus software, also known as scareware, commonly pops up spooky-looking warnings that a user's computer is infected with malware, even though it does not. The software then offers to clean-up the infection, but demands payment first.
Of course, you've then given your credit card details to someone who has already proved themselves not above dirty tricks. Don't be surprised if your problems have only just begun.

The lesson here is clear. It's good to be interested in computer security, and to take notice of security warnings and the latest updates when they become available.
But you also need to check who is giving you the security advice.
Because if the person who is telling you to install a security update can't be trusted, or isn't who they claim to be, there's a chance you could be heading into even bigger danger.
